In a small bowl, combine all the ingredients thoroughly and store in an airtight container for up to 3 months.

Preheat the oven to 350 degrees F.

Rub the chicken on all sides with the oil and sprinkle with the poultry rub. Place the chicken upright on a vertical roaster, making sure the top of the roaster pokes through the neck cavity.

Place in a small roasting pan and add enough chicken stock or water to come about 1/4-inch up the side of the pan. Roast until the juices run clear and the chicken reaches an internal temperature of 165 degrees F, 1 hour to 1 hour and 15 minutes.

Remove from the oven and carefully transfer from the roaster to a platter. Let rest for 10 minutes before carving.

To serve, carve the chicken into pieces. Serve hot with the rice and vegetables.
